Michelle ordered two large pizzas. Each pizza was cut into eight slices of equal size. She gave 1/2 of the pizza to Chris, 3/8 of a pizza to John, and 1/4 of a pizza to Sally. How many slices of pizza were left?
Well first you want to get the denominators to be matching
so 1/2 = 4/8 and 1/4 = 2/8.
Then add them together (Make the denominator 16 since there is two pizzas)
4/16 + 2/16 + 3/16 = 9/16
To find the remaining
16/16 - 9/16 = 7/16
Simplify if possible, but you can't in this problem.
So the answer is 7/16 slices are left

Your percentages don't add up right: 1/2 + 3/8 +1/4=1 1/8 is wrong. They must be equal to or less than 1.
FIrst turn all the fractions into 8ths (this is assuming she gave 1/2 of A pizza to Chris)
1/2 =4 / 8 to Chris
3/8 to John
1/4 = 2 /8 to Sally
2 pizzas = 16/8 pizzas
SO the question says she gave away 4/8 + 3/8 + 2/8 = 9/8ths of the pizza
16/8 - 9/8 = 7/8 of a pizza left (seven slices)
IF she gave 1/2 of THE (two) pizzas to Chris she is left with one pizza (8 slices)
then she gives 3/8 to John she now has 5/8 pizza left (5 slices)
then she gives 2/8ths to Sally so she is left with 3/8th pizza (3 slices)
The wording of the pizza she gave to Chris is a little unclear.
